I jus found out that my head gasket are bad.. how far can i trust it? on 2002 Dodge Ram 1500

i jus move to Missouri, from Fla. an bought the truck n Fla. right before i move here. I cant change the heads this month.. Can i trust it to go back and forth to my doctors a hour away?? I keep an eye on the gages an check the water level daily. I have use lquid glass, that didnt last long, cause i needed anti freeze, then we added some other gasket sealer. my water pump was change after that.. can i drive it alil. longer??

LOL!! thats why my radiator crack,Had to change it,we were pouring water in 1 day an it was pouring out on the sides of the radiator and also the water pump last week.Is that why my heater dont get warm too?
